Abstract

Sea bream and sea bass are highly adaptable to different culture systems, making them well suited for aquaculture. Their delicious flesh has contributed to the growing popularity of the aquaculture industry. This research was conducted to evaluate the grow-out of European Sea bream and Gilthead Sea bass in the eastern Libyan coast of the Mediterranean Sea. Fingerlings of the fish obtained from the natural brackish water of the Eastern Libyan coast and stocked in earthen ponds supplied with brackish water. A 120-day rearing trial was conducted which showed that the growth performance of Seabream and Seabass in this experiment varied significantly, even though both were fed similar levels of dietary proteins. The weight gained, specific growth rates, and protein efficiency ratio were significantly higher (P˂0.05) in Seabream compared to Seabass. The survival was not significantly different between the two species at the end of the experimental period. The feed conversion ratio was lower in Seabream (1.77) compared with Seabass (1.98). The moisture (68.10 ± 0.72%) and ash contents (3.90 ± 0.04%) were significantly higher in Seabass, while the crude protein (17.39 ± 0.17%) and lipids (11.36 ± 0.24%) were significantly higher in Seabream in this experiment. The Libyan Mediterranean coast is suitable for the grow-out of the two species, and the Seabream showed better growth and higher nutrition quality compared with Seabass.
